Does Engine It Stirling Work

Does Engine It Stirling Work

(See "Have You Driven a Fjord Lately?" in the August issue of Business 2. "I took him up to New Hampshire and we spent half the night speculating about how cool the world could be if you put the right technologies in the right place at the right time," says Kamen. . The marketplace wasn't ready for his vision. "The gasses used inside a Stirling engine never leave the engine. If the Stirling engine is scalable so that it could be put into 4 wheelers or even mid sized boats it could really change the face of power consumption my state and probably the whole world.

The biggest obstacles to popular Stirling cars were long warm-up time, and somewhat lower power density, but now in the era of PHEVs (and heavy smog gear requirements) neither matters anymore. Kamen is an incredibly creative, intelligent individual. Current 5490 activity focuses on free-piston Stirling convertors for deep space missions: Radioisotope Power System for Deep Space Missions Deep Space Solar Stirling Power System GRC Assessment of Stirling Technology Provides Critical Data Leading Towards Flight Readiness 55 Watt Stirling Power Convertors Operating at GRC! Test Schedule and Test Data for the 55 Watt TDC's 55 Watt Stirling TDC's Completes Microgravity Emissions Lab (MEL) First integrated Stirling/Hall Thruster Test TDC's undergoing Structural Dynamics Testing The below links are included for reference and historical information regarding past work. This means it runs on heat from an external source. Green Wombat: Dean Kamen's Stirling Solution « Green Media Payday: Discovery Buys TreeHugger Dean Kamen's Stirling Solution In a world of Stepford executives who never deviate from the corporate party line, there's something refreshing about an entrepreneur willing to take a tumbleliterallyfor his latest innovation. A million local generators are way more efficient than 1 big one in a remote location, and the efficiency gain directly translates to a prodigal rembrandt return son reduction in overall power generation, energy costs and carbon emissions.

Other companies including BMW are already talking about harvesting the waste heat from their engines to improve efficiency. The marketplace wasn't ready for his vision.
There are only so many watts available per square meter coming down from the sun, and by the time the sun's energy makes it to the ground, it is no where near the 1,365 or so watts it is up above the atmosphere.

You can also run ICE engines off of biofuels, although the Stirling should be more efficient and is much more friendly to a wide range of convenient, safe biofuels. I cannot find one for sale to use as a power generator for my cabin, located in 100 aacres of trees.
I think we can develop septic tanks that produce bio-gas and a small scrubber/compressor which can clean the gas for storage in a gas bag. " So Willums shipped a Think City to Kamen, who is now modifying the two-seater coupe to carry a Stirling engine (photo at right) powered by veggie oil, for instance. Too, too late to this discussion to be particularly releventbut I DO have to comment on how very regressive the average US commentator is. I use to work there and wrote a lot of the code that runs in the eNC. Surely you are not going to be feeding cow dung into your Think City? And without some kind of huge solar ray collection mirror or something, the car is not going to be solar powered. It would make a clean efficient low emission solution. The Stirling engine (in a PHEV, which is what we're talking about making) is definitely better, and indeed is a paradigm shift away from pollution, but global warming isn't the main point.
Bottom line isMr Kamen's attempts fly in the face of the mass ignorance, lethagy, and belief that 'we' know it all are totally honourable, and admirable.

In June, Green Wombat visited Westwind, Kamen's estate outside Manchester, New Hampshire, to talk to the Segway inventor about his plans to install a Stirling heat engine in an electric car made by Norway's Think. There are three basic types of stirling engine:Alpha Stirling EngineThis engine has two separate power pistons, one hot and one cold.
Parking your car in the garage where you might have some leaky cans of paint thinner filling the room with fumes all day might result in an unhappy event.
Shaltens * an asterisk indicates an external link. A Stirling engine can run on a pretty small temperature differential but you won't get much power out of it. About 7 years left to equalize the mad CO2 buildup. There is also a bit of a safety issue when you have external combustion in a moving vehicle. I hope Kamen is really making some improvements because the power to weight ratio of other modern Stirlings is still so abysmal that they are far too heavy to put in a vehicle.
This expansion and contraction works forces a working piston which in turn drives a crankshaft. In addition to external combustion heat sources, it can recapture heat generated by the battery and braking among. The temperature differential between the interior of a vehicle and the outside won't get you far, and there's an insignificant amount of heat energy in that small volume of new concept hair goods air anyway. That can be addressed, but it's more of a concern than an internal combustion engine. 0 Beta All B2 Blogs Business 2. And to respond to KillJoy, a Stirling Engine only needs a temperature differential to run. Kamen invented the Teletrol and his company of the same name remotely operates the heating yacht charter british columbia and air-conditioning systems of buildings like the Sydney Opera House. My understanding is that vehicle interiors get well above 100 degrees. I'd love to see you do an article on Plasma Gasification in regards to dealing with our dump/garbage issues.
The advantage of this design is that it is mechanically simpler and the disadvantage is the lower compression ratio. There are lots of claims about the sterling engines but I have only seen toy models for sale.

“If you have enough Thinks out there you would literally change the architecture of the grid,” says Kamen, taking Green Wombat for a drive around Westwind and past his wind turbine before parking the blue Think City near his pair of Enstrom helicopters. I can still see another advantage being that it might be extremely flexible on the type of fuel burnt.
"You get home and you plug your house into it. There are no exhaust valves that vent high-pressure gasses, as in a gasoline or diesel engine, and there are no explosions taking place. ) "The big advantage is once we’re in production with that engine, where it will really be uniquely valuable is to the 1. It does indeed generate power the dirty old fashioned way, but the point is about efficiency. What is the heat source for the Think car? Just a correction, it's not a Teletrol but an eNC built by Teletrol, a company that Dean bought to make building automation equipment.
The Stirling engine would then recharge the car's battery for the commute home. "I need some killer app to put this thing into production. You could use fossil fuels but sunlight from a solar collector would work just as well.
Much of the state's northern coast from about Nome is bereft of natural fuels. . They have already moved to the US where there are REALLY entrepenaurial financeers, still. Gamma Stirling EngineThis is a beta Stirling engine accessory computer other product in which the power piston is not mounted coaxially to its displacer piston. You probably won't see a Stirling in a Toyota (TM) or Ford (F) but the device gives Think another power plant to offer its customers.
If you have a TypeKey or TypePad account, please You are currently signed in as Email Address: green bay packers apparel (Not displayed with comment. " Posted by Todd Woody at 10:47 AM Permalink Listed below are links to weblogs that reference Dean Kamen's Stirling Solution: That sounds so awesome. Y'all have a nice day now, y' hear. The displacer piston does not extract any power from the expanding gas but only serves to move the working gas from the hot heat exchanger to the cold heat exchanger.

" He shows off power plugs behind the scooter's seat.
.
The same will probably hold true for this latest project. I wish we had a couple of Aussie developers of like ability. Stirling EngineDiracDelta Science & Engineering Encyclopedia # A B C D E F G H I J K L M N O P Q R S T U V W X Y Z HomeCalculationsContactsConversionsHelpLinksSubjects Stirling EngineAn external combustion engine. If he says it's possible, it's possible.
I'm very curious about its efficiency and the mechanism it uses to accomplish this. If you pay attention to what is said in the article, the car is not powered by the Stirling engine. I wonder if the erotic doctor storylatest invention low swirl injector technology could be made to work with liquid fuels like gasoline? Then you would have your killer application for vehicles. The promise of the Stirling engine is a lot like the promise of the fuel cell, except that it uses (spruced-up) technology from decades ago instead of decades from now. The Stirling cycle uses an external heat source, which could be anything from gasoline to solar energy to the heat produced by decaying plants. ) But first, Kamen wanted to demo the scooter (photo above) to show how a virtually greenhouse gas-free Stirling engine could extend the range of an electric vehicle by trickle-charging the battery. Because of this, Stirling engines are very quiet. As the gas is heated it expands and as it is cooled it contracts. When electricity demand peaks during the day, thousands of Thinks plugged in at office parks could feed power back to the grid so utilities like PG&E (PCG) and Edison (EIX) could avoid having to fire up planet-warming power plants. ) "We run two villages in Bangladesh on Stirlings that run on freakin' cow dung," says Kamen, who envisions Stirling engines powering the world's off-the-grid villages and using the waste heat produced by the engine to purify water. for those not inclined to click through. I live up in Alaska, USA and while most the cities have fairly dependable power a lot of the bush communities don't. " Perhaps you should do an article on "Whispertech" in New Zealand who already market such machines -(home heating and power generation. ) Kamen heads to the control room of his 33,000-square foot house. It's not a zero emission system, it's a reduced-emission system. Pulling up to the pump at a gas station could be particularly exciting. As another Alaskan, I am also interested in this technology. We are building small, advanced bio-digesters for use on organic dairy farms.

Kamen met Think CEO Jan-Olaf Willums last year at MIT. In uber-inventor Dean Kamen's case that meant crashing his Stirling electric hybrid scooter in front of Green Wombat and a photographer. Anywhere in the bush where they burn wood or coal for heat in the winter could use shape of my heart guitar tab heat/stack-robbers to power the Stirlings. Sure, you might be able to get reasonable power output if you park a solar collector next to your house, or burn cow dung in a village somewhere, but the total energy contained in a car parked in an open parking lot pales in comparison to the energy needed to drive that car home in the afternoon. This design is often used in multi-cylinder Stirling engines. does a Stirling Engine Work (slide tutorial) Refrigerator/Freezer Development Project Stirling Conversion System (Solar Stirling) Stirling Engines, 12. The Toyota Prius already achieves high efficiencies while producing essentially no noise and tiny amounts of smog. There were a lot of rumors about the segway before its release and really it was an interesting idea, just one that a lot of pepole didn't see as a needed thing. They can use virtually any fuel source to heat a sealed container containing a gashydrogen or helium, for instancethat expands and contracts to drive a piston and produce electricity. I have proposed linking one famous poem for grandmother to a WHISPER GEN unit for a client. As other commenters pointed out, fossil fuel is needed to provide the heat source for a Stirling equipped vehicle. Is the Stirling hybrid's efficiency going to be better than an advanced ICE hybrid? How is this better than a Toyota system, and how much better? Kamen is definitely a brilliant guy, but he's not beyond a hare-brained idea or two. See also: Engine, Vacuum Engine.

So it is not "virtually green house gas-free" as the article said. On the Right, a mock up of a Brayton engine, and two operating Administrator O`Keefe balances a nickel on one of the operating low vibration Stirling convertors GRC has actively been involved with Stirling technology for over 25 years including large free-piston engines, small free-piston radioisotope systems, automotive kinematic engines, and component technologies. High efficiency is no match for the basic physics of moving a one or two thousand pound vehicle down the road, even with reasonably low coefficients of drag. You can invent a new lightbulb to change, but you can't change people to accept a new lightbulb. 0: Mac, iPod, iPhone Dawn Patrol: Venture Capital only god can judge me Green Wombat: Environment Netly News: Internet Small Change: Small-Cap Tech Stocks The Startup Game: New Companies Third Screen: Wireless The Utility Belt: Gadgets.
But the big difference is that the Stirling decimates the temptation to emit local pollution (including noise). Stirling engines could possibly off-set some of these costs.
People will always switch to something that makes life better, if some SOB does not buy it up and put it on the shelf. He's not some crackpot who thinks he can break the laws of physics with his perpetual motion machine; he wouldn't be spending the money he is on this project if he didn't know it can work. (The scooter uses a small can of propane as the fuel source. And one way to do that would be to create the world’s first hybrid Stirling electric car.

You can invent a new lightbulb to change, but you can't change people to accept a new lightbulb. 6 billion people on this plant who’ve never another from mother one single used electricity," says Kamen. Also, would not a heat sink of the stirling engine connected to BEV lithium battery packs result in recovered electrical energy while at the same time removing unwanted heat that can reduce battery efficiency and even cause damage if temp specs are exceeded? There's only so much total energy in any temperature differential, and that's going to be the limitation with any Stirling power solution. Where is Kamen getting his heat? from the sun? No from fuel or electricity which generate green house gases. I mean, questioning the long ack efficiency of a Stirling engine with facile comments about cow dung! Pathetic.
. Smog is an ICE/petroleum partnership-caused problem. The same will probably hold true for this latest project. " Over the past decade, Kamen, who made a fortune as inventor of the insulin pump and other medical devices, has spent some $40 million developing Stirling engines. . (Incidently, any dung is the perfect source of low temp & long slow cooking of magnificent mealsask any Indian grand-mother).
He has been working on this for around 7 years as I read about this here in silicon valley at that time when Doeer was touting this and the Ginger/Segway as earth shattering inventions.
Kamen failed miserably with his Segway.
"Say you're in Bangladesh or anywhere in the world where people don’t have electricity," says Kamen, dusting himself off and not missing a beat.
